Augmented Reality for UE4

Hi .
I package apk file with obb, but it wont initialize camera on device.
The game doesn’t copy Content/ARToolkit folder to mobile device, even thou i added Aditional non-asset folder to copy, and aditional non-asset folder to package.
Tried it on Xperia Aqua M4, Galaxy Mega and Galaxy S6 Edge.
When i copy and create folder manualy, camera resloution is 2x2 until marker is recongized.
What could be the problem?
